Installed RW Enhancer Pro shader preset in an attempt to make German signal speed signs more visible.

1. Sign in to rwcentral.com
2. Download the shader file
3. Open RW Shader
4. Import shader
5. Press Install / Update button.

Seems to be a bit better. Time will tell...

As per https://forums.dovetailgames.com/threads/morning-haze-issue.40083/ - editing career.xml resulted in my losing all of my TSC progress. Tried forum suggestions of deleting SDBcache etc but nothing has worked.
